Abstract

Изобретение относится к способу регенерации жидких кристаллов электроуправляемой системы с переменным рассеянием света, содержащей подложку (4, 5), несущую жидкокристаллический элемент (3) между двумя электродами (1, 2), соединенными со схемой электрического питания. Способ содержит этапы, на которых обеспечивают данные для регенерации, содержащие продолжительность регенерации DT и по меньшей мере одно заданное значение С регенерации, обеспечивают программирование, содержащее сравнение рабочих данных с заданным значением С регенерации, обеспечивают автоматическую регенерацию путем автоматического отключения электрической схемы в течение продолжительности DT после достижения заданного значения или заданных значений С, и обеспечивают программирование для принятия решения относительно принудительного режима во время текущей регенерации в зависимости от данных о предшествующем использовании и/или о контексте использования. Изобретение также относится к схеме электрического питания и устройству для регенерации.The invention relates to a method for regenerating liquid crystals of an electrically controlled system with variable light scattering, comprising a substrate (4, 5) carrying a liquid crystal cell (3) between two electrodes (1, 2) connected to an electric power supply circuit. The method comprises the steps of providing data for regeneration, containing the regeneration duration DT and at least one regeneration preset value C, providing programming comprising comparing the operating data with the regeneration preset value C, providing automatic regeneration by automatically turning off the electrical circuit during the DT duration after reaching the setpoint or setpoints C, and provide programming to make a decision on the forced mode during the current regeneration depending on the data about the previous use and / or about the context of use. The invention also relates to an electrical supply circuit and a regeneration device.
